Abstract

The invention features a vital sign monitor that includes: 1) a hardware control component featuring a microprocessor that operates as interactive, icon-driven GUI on an LCD; and, 2) a sensor component that connects to the control component through a shielded coaxial cable. The sensor features: 1) an optical component that generates a first signal; 2) a plurality electrical components (e.g. electrodes) that generate a second signal; and, 3) an acoustic component that generates a third signal. The microprocessor runs compiled computer code that operates: 1) the touch panel LCD; 2) a graphical user interface that includes multiple icons corresponding to different software operations; 3) a file-management system for storing and retrieving vital sign information; and 4) USB and short-range wireless systems for transferring data to and from the device to a PC.

Claims6

Dependent claims

A hand-held vital signs system, comprising:

a housing comprising a microprocessor that is operably connected to a touch screen display on a surface of the housing to provide operation controls for the vital signs system on an icon-driven graphical user interface;
at least two electrodes operably connected to the microprocessor configured to measure an electrical signal which is processed by the microprocessor to provide an ECG waveform;
and
a first sensor operably connected to the microprocessor configured to measure a low-frequency waveform comprising frequency components of between 40 Hz and 500 Hz indicative of heart valve operation;
a second sensor operably connected to the microprocessor configured to measure an optical waveform,
wherein the microprocessor is configured to collectively process the low-frequency waveform and the ECG waveform to determine a pre-ejection period, to collectively process the optical waveform, the ECG waveform and the pre-ejection period to determine a vascular transit time, and to determine a blood pressure value using the vascular transit time.
